are used to connect two active ethernet network components
together over a fiber optic cable. Radiant’s unique technology
allows the same transceiver to be used for connecting 10BaseT or
100BaseT components together. The Radiant Communications
Series DL221/DL221A transceivers allow for extended fiber transmission distances -- in many cases greater than 100 KM. In addition, the Series DL221A transceivers allow for bi-directional, full
duplex transmission between ethernet components over a single
optical fiber.
It is convenient to think of the Series DL221/DL221A transceivers
as having two sections -- an electrical section, which interfaces to
the ethernet component; and an optical section, which interfaces to
the fiber optic cable.

The optical section is a 100BaseFX connection at all times. The
DL221 family of transceivers supports bi-directional transmission
over two single mode fibers. The DL221A family of transceivers
supports bi-directional transmission over a single mode fiber. In
both cases, Radiant’s technology allows for extended transmission
distances beyond the ethernet standard.
If the problem persists after carrying out the procedure, do the
following: exchange two different channels with one another
(both copper and fiber connections), and re-perform the requested
setup. If the problem still persists, there is probably some sort of
general network failure. Contact the Radiant Communications
technical support department for assistance.
